r residing at Renders, Denmark, have in- -a'ords a considerably more advantageous thermal utilization of the fuel over` the methods hitherto known :it a very great simplicity of the design of thelengine. The acceptance of this method renders the use of many parts dispensable, vwhich were'hitherto considered as drawbacks in engnes'of a' similar kind; as for' instanctiie compressor the igiition cap of the Brons engine the glowhead 'with heating lampand the cle-- or the dripping cooling water in the vglowhead engine, the carburetor devices for 'l 'd fuels in carbureter engines and theliA c. Notwithstanding the simplicity of the mechanism required for its perfomance, the noi-el method allows of the use of easily or not'eas'ily volatile fuels, and owing to the high ratio the compression of a good thermal 'utilization of fuel, whether'the enginesloe constructed on the four-cycle, the two-cycle.

It is not necessary that this mixture is infiammable, particularly when a not readily volatile fuel is used. As Witlrtlie progress of the compression also the heat of the compression `will increase, the hitherto only mechanically.4 didusedparticles of fuel will he evaporated and form with the air a mixture vof fuel vapor and air, which at a given ratio of the mixture Will become inflammable at a higher compression. order to prevent a premature ignition of this mixture, when the compression heat rises ,Still further, one or several further for the injection air of the Diesel engine *L portions of nh# mechanically diffused fuel are introduce'dldui'ing the'further compression period into the already existing miicture of .fuel and air. .This renewed intro,
